NAME
      rpcsvcreg:   svcfreeargs, svcgetargs, svcgetreqset,
      svcgetrpccaller, svcrun, svcsendreply - library routines for RPC
      servers

DESCRIPTION
      These routines are part of the RPC library which allows C language
      programs to make procedure calls on other machines across the network.

      These routines are associated with the server side of the RPC mechanism.
      Some of them are called by the server side dispatch function, while
      others [such as svcrun] are called when the server is initiated.

   Routines
      #include <rpc/rpc.h>

      int
      svcfreeargs(const SVCXPRT *xprt, const xdrproct inproc, char *in);

            A function macro that frees any data allocated by the RPC/XDR
            system when it decoded the arguments to a service procedure using
            svcgetargs.  This routine returns 1 if the results were
            successfully freed, and 0 otherwise.

      int
      svcgetargs(const SVCXPRT *xprt, const xdrproct inproc, caddrt *in);

            A function macro that decodes the arguments of an RPC request
            associated with the RPC service transport handle xprt.  The
            parameter in is the address where the arguments will be placed;
            inproc is the XDR routine used to decode the arguments.  This
            routine returns 1 if decoding succeeds, and 0 otherwise.

      void
      svcgetreqset(fdset *rdfds);

            This routine is only of interest if a service implementor does not
            call svcrun, but instead implements custom asynchronous event
            processing.  It is called when poll has determined that an RPC
            request has arrived on some RPC file descriptors; rdfds is the
            resultant read file descriptor bit mask.  The routine returns when
            all file descriptors associated with the value of rdfds have been
            serviced

      struct netbuf *
      svcgetrpccaller(const SVCXPRT *xprt);

            The approved way of getting the network address of the caller of a
            procedure associated with the RPC service transport handle xprt.

      void
      svcrun(void);

            This routine never returns.  It waits for RPC requests to arrive,
            and calls the appropriate service procedure using svcgetreqset
            when one arrives.  This procedure is usually waiting for a poll
            library call to return.

      int
      svcsendreply(const SVCXPRT *xprt, const xdrproct outproc,
            const caddrt *out);

            Called by an RPC service's dispatch routine to send the results of
            a remote procedure call.  The parameter xprt is the request's
            associated transport handle; outproc is the XDR routine which is
            used to encode the results; and out is the address of the results.
            This routine returns 1 if it succeeds, 0 otherwise.
